**Creating index.html** I’m focusing on creating an index.html file. I need to check the current working directory and implement a polished design. I’ll write the file while ensuring that all sounds synth with WebAudio. I want a grid that’s 4x16 and clickable, set to BPM. Maybe I should also consider adding transport controls, a visual playhead, and keyboard functionality. It seems like a single file approach might be the best way to craft this!

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
